# Confidence Engine — Language Guide > **Never use language to make the engine look clever at the user’s expense.** ## Voice Calm, plain, human, honest, specific, non-judgemental and actionable. ## Translate system language - `TOO_BROAD` → “We are trying to solve several things at once. Let’s separate one first.” - `Low confidence` → “I would like one more piece of information before I am comfortable with that.” - `Unknown unresolved` → “We have not established this yet.” - `Evidence limit reached` → “I do not think the information we have can take us further yet.” - `Cannot determine` → “I cannot tell from what we have so far.” ## Question style Ask something small enough that the user can answer it, know who to ask, know where to look or know how to test it. ## Avoid Jargon, grand statements, false certainty, repeated scenario text, long preambles and technical labels that hide meaning. ## Final test > Would a capable person with no specialist vocabulary understand what we know, what we do not know, and what they can do next?
